玩家控制脚本设计思路

1. 代码演变过程

1.1 初始阶段：单一Player类实现

最初的设计可能是一个包含所有功能的Player类：

public class Player : MonoBehaviour
{private CharacterController controller;private Animator animator;[SerializeField] private float speed = 4f;private Vector3 move;private float gravity = -9.81f;private Vector3 velocity;void Awake(){controller = GetComponent<CharacterController>();animator = GetComponent<Animator>();}void Update(){HandleMovement();HandleGravity();}private void HandleMovement(){float horizontal = Input.GetAxis("Horizontal");float vertical = Input.GetAxis("Vertical");move = new Vector3(horizontal, 0, vertical);// ... 其他移动逻辑}
}

这种设计的问题：

所有功能耦合在一起
代码复用性差
难以扩展新角色类型
维护成本高

1.2 第一次重构：提取基类

识别出通用功能，创建抽象基类：

public abstract class Character : MonoBehaviour
{protected CharacterController controller;protected Animator animator;[SerializeField] protected float speed = 4f;protected Vector3 move;protected float gravity = -9.81f;protected Vector3 velocity;protected virtual void Awake(){controller = GetComponent<CharacterController>();animator = GetComponent<Animator>();}protected virtual void Update(){HandleMovement();}protected abstract void HandleMovement();
}

1.3 当前架构：功能模块化

1.3.1 Character基类（最终版本）

public abstract class Character : MonoBehaviour
{// 基础组件protected CharacterController controller;protected Animator animator;// 移动相关参数[SerializeField] protected float speed = 4f;protected Vector3 move;// 物理相关参数protected float gravity = -9.81f;    protected Vector3 velocity; protected virtual void Awake(){controller = GetComponent<CharacterController>();animator = GetComponent<Animator>();} protected virtual void Update(){HandleMovement();}// 抽象方法强制子类实现protected abstract void HandleMovement();
}

1.3.2 Player类（最终版本）

public class Player : Character
{#region 移动系统[SerializeField] private float speedMax = 6f;private float currentSpeed;private bool isShift;#endregion#region 跳跃系统private bool isGrounded;[SerializeField] private float jumpHeight = 3f;[SerializeField] private LayerMask groundMask;[SerializeField] private Transform groundCheck;[SerializeField] private float groundDistance = 0.15f;#endregion#region 攻击系统private bool isAttacking;private float lastAttackTime;#endregionprotected override void Update(){isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);base.Update();HandleGravity();HandleAttack();}#region 移动系统实现protected override void HandleMovement(){if(isAttacking){move.Set(0, 0, 0);animator.SetFloat("Speed", 0);return;}// 基础移动输入float horizontal = Input.GetAxis("Horizontal");float vertical = Input.GetAxis("Vertical");move = new Vector3(horizontal, 0, vertical);// 移动规范化if(move.magnitude > 1f){move = move.normalized;}// 45度视角调整move = Quaternion.Euler(0, -45f, 0) * move;// 角色朝向if(move != Vector3.zero){transform.rotation = Quaternion.LookRotation(move);}// 冲刺系统HandleSprint();// 应用移动controller.Move(move * currentSpeed * Time.deltaTime);// 动画控制animator.SetFloat("Speed", move.magnitude);animator.SetBool("IsShift", isShift);}private void HandleSprint(){if(Input.GetKey(KeyCode.LeftShift)){currentSpeed = speedMax;isShift = true;}else {currentSpeed = speed;isShift = false;}}#endregion#region 重力系统实现private void HandleGravity(){animator.SetBool("isAir", !isGrounded);if(isGrounded && Input.GetButtonDown("Jump")){velocity.y = jumpHeight;}velocity.y += gravity * Time.deltaTime;controller.Move(velocity * Time.deltaTime);}#endregion#region 战斗系统实现private void HandleAttack(){if(Input.GetButtonDown("Fire1")){if(!isAttacking){isAttacking = true;animator.SetTrigger("Attack");}else{string triggerName = animator.GetCurrentAnimatorClipInfo(0)[0].clip.name;float triggerProgress = animator.GetCurrentAnimatorStateInfo(0).normalizedTime;// 连击系统if(triggerName != "LittleAdventurerAndie_ATTACK_03" && triggerProgress > 0.3f && triggerProgress < 0.7f){animator.SetTrigger("Attack");}}}}// 动画事件触发的特效public void PlayBlade01() => VFXManager.instance.Play("Particle Sword Blade 01");public void PlayBlade02() => VFXManager.instance.Play("Particle Sword Blade 02");public void PlayBlade03() => VFXManager.instance.Play("Particle Sword Blade 03");private void OnAttackEnd(){isAttacking = false;}#endregion
}

2. 详细设计分析

2.1 基类设计要点

组件封装
- 将CharacterController和Animator组件封装在基类中
- 使用protected访问级别允许子类直接访问
- 在Awake中统一初始化
移动系统框架
- 定义基础移动变量（speed, move, velocity）
- 提供抽象的HandleMovement()方法
- 实现基础的Update循环
物理系统基础
- 封装重力相关参数
- 提供基础的物理运动框架

2.2 Player类实现分析

移动系统

protected override void HandleMovement()
{// 1. 状态检查if(isAttacking) { ... }// 2. 输入处理float horizontal = Input.GetAxis("Horizontal");float vertical = Input.GetAxis("Vertical");// 3. 移动计算move = new Vector3(horizontal, 0, vertical);// 4. 规范化处理if(move.magnitude > 1f) { move = move.normalized; }// 5. 视角调整move = Quaternion.Euler(0, -45f, 0) * move;// 6. 朝向控制if(move != Vector3.zero) { ... }// 7. 移动应用controller.Move(move * currentSpeed * Time.deltaTime);// 8. 动画更新animator.SetFloat("Speed", move.magnitude);
}

跳跃系统

private void HandleGravity()
{// 1. 地面检测animator.SetBool("isAir", !isGrounded);// 2. 跳跃输入if(isGrounded && Input.GetButtonDown("Jump")){velocity.y = jumpHeight;}// 3. 重力应用velocity.y += gravity * Time.deltaTime;controller.Move(velocity * Time.deltaTime);
}

战斗系统

private void HandleAttack()
{// 1. 攻击输入检测if(Input.GetButtonDown("Fire1")){// 2. 状态检查if(!isAttacking){// 3. 开始攻击isAttacking = true;animator.SetTrigger("Attack");}else{// 4. 连击处理string triggerName = animator.GetCurrentAnimatorClipInfo(0)[0].clip.name;float triggerProgress = animator.GetCurrentAnimatorStateInfo(0).normalizedTime;if(可以连击条件){animator.SetTrigger("Attack");}}}
